  21 # This is the GCC target-specific configuration file
  22 # where a configuration type is mapped to different system-specific
  23 # definitions and files.  This is invoked by the autoconf-generated
  24 # configure script.  Putting it in a separate shell file lets us skip
  25 # running autoconf when modifying target-specific information.
  26
  27 # When you change the cases in the OS or target switches, consider
  28 # updating ../libgcc/config.host also.
  29
  30 # This file switches on the shell variable ${target}, and also uses the
  31 # following shell variables:
  32 #
  33 #  with_*               Various variables as set by configure.
  34 #
  35 #  enable_threads       Either the name, yes or no depending on whether
  36 #                       threads support was requested.
  37 #
  38 #  default_use_cxa_atexit
  39 #                         The default value for the $enable___cxa_atexit
  40 #                       variable.  enable___cxa_atexit needs to be set to
  41 #                       "yes" for the correct operation of C++ destructors
  42 #                       but it relies upon the presence of a non-standard C
  43 #                       library function called __cxa_atexit.
  44 #                         Since not all C libraries provide __cxa_atexit the
  45 #                       default value of $default_use_cxa_atexit is set to
  46 #                       "no" except for targets which are known to be OK.
  47 #
  48 #  gas_flag             Either yes or no depending on whether GNU as was
  49 #                       requested.
  50 #
  51 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
  52 #                       requested.
  53
  54 # This file sets the following shell variables for use by the
  55 # autoconf-generated configure script:
  56 #
  57 #  cpu_type             The name of the cpu, if different from the first
  58 #                       chunk of the canonical target name.

  61 #
  62 #  tm_file              A list of target macro files, if different from
  63 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
  64 #                       per target in a way like this:
  65 #                       tm_file="${tm_file} dbxelf.h elfos.h svr4.h ${cpu_type.h}/elf.h"
  66 #                       Note that the preferred order is:
  67 #                       - specific target header "${cpu_type}/${cpu_type.h}"
  68 #                       - generic headers like dbxelf.h elfos.h, etc.
  69 #                       - specializing target headers like ${cpu_type.h}/elf.h
  70 #                       This helps to keep OS specific stuff out of the CPU
  71 #                       defining header ${cpu_type}/${cpu_type.h}.
  72 #
  73 #                       It is possible to include automatically-generated
  74 #                       build-directory files by prefixing them with "./".
  75 #                       All other files should relative to $srcdir/config.
  76 #
  77 #  tm_p_file            Location of file with declarations for functions

  84 #                       different from "$cpu_type/$cpu_type.md".
  85 #
  86 #  tmake_file           A list of machine-description-specific
  87 #                       makefile-fragments, if different from
  88 #                       "$cpu_type/t-$cpu_type".
  89 #
  90 #  extra_modes          The name of the file containing a list of extra
  91 #                       machine modes, if necessary and different from
  92 #                       "$cpu_type/$cpu_type-modes.def".
  93 #
  94 #  extra_objs           List of extra objects that should be linked into
  95 #                       the compiler proper (cc1, cc1obj, cc1plus)
  96 #                       depending on target.
  97 #
  98 #  extra_gcc_objs       List of extra objects that should be linked into
  99 #                       the compiler driver (gcc) depending on target.
 100 #
 101 #  extra_headers        List of used header files from the directory
 102 #                       config/${cpu_type}.
 103 #
 104 #  use_gcc_tgmath       If set, add tgmath.h to the list of used header
 105 #                       files.
 106 #
 107 #  use_gcc_stdint       If "wrap", install a version of stdint.h that
 108 #                       wraps the system's copy for hosted compilations;
 109 #                       if "provide", provide a version of systems without
 110 #                       such a system header; otherwise "none", do not
 111 #                       provide such a header at all.
 112 #
 113 #  extra_passes         List of extra executables compiled for this target

 150 #
